PNEUMATIC CONVEYING IN THE VERTICAL PIPELINE OF AIR LIFT

Abstract

In this paper the authors present a procedure for determining pressure drop caused by solid material moving in the vertical pipeline of an air lift. This method can be used to determine important parameters - with regard to the expansion of the conveying gas - such as acceleration and velocity of particles, change of gas velocity along the pipeline, etc. In this paper the authors have neglected the tightening effect on the cross-section created by the solid material. It is in a further paper, to be published later, that they shall point out what sort of mistakes this negligence causes in each physical parameter.
